lMPROVENlENT'IN APPARATUS FOR SPREADING MEDICAL PLASTERS.

The Schedule referred to in these -Letters Patent and making parl: of the same.

I, ADOLPH J. SCHAFHIRT, of the city and county of lVashington, in the District of Columbia, have inparatus for 'Spreading Medicinal Plasters, ot' which the following is a speciiication, reference being had to the accompanying drawingrnakiug a part ofthe same. The nature and object of my invention is to make an adjustable apparatus, by means of two perforated plates sliding one upon the other, whereby differentsized plasters can be made with the same, such want being long felt by the druggst and apotheeary. In the drawing- Figure l represents the apparatus in common use; Figure 2 represents my improved adjustable appa- Figures 3, 4, 5, 6, and 7 show modifications or equivalents of the same.

In fig. 1-

AA represents a block, to which the lid a` is hinged, the latter holding secure the skin or fabric (on which the plaster is to be spreadiupon the former, for which purpose any ordinary clamping apparatus can be used. In my improvement I use two plates, the upper sliding upon the lower, which lower one `I propose hingng to a block, as is usually done; but this is not necessary.

B represents the lower plate, from which project two screws or other pins, I1, which pass through slots c at opposite corners of top plate` D. Besides the It will readilyrbe seenhow, by moving the top plate D up or down and sidewise, the space O can be contracted or enlarged, thus enabling the apothecar-y to regulate the size of his plasters, which vary from 10 12 to 1X2, 85e.

In either of the' platesB or DI can make openings cl for the plaster-s to be applied behind the ears ;A

and two sides ot either plate (the lower preferredimay be marked off in inches and half inches, er smaller, as seen in fig. 1, by which to gauge the sizeof the plasters. l

where screw-pins are used.

Fig. 3 shows a modification, showing two movements, one vertical and the other horizontal, l) b showing the pins which pass through the slots,

Fig.,5 shows a variation, not differing essentially from the device shown iu g. 3, having two movements'. f l

Fig. 4 shows an adjustment by means of two or more pivoted arms. i

I1igs.6 and 7 show other variations of the top plate,

which will be readily understood, and on these plates The pins b b may have clamp-buttons on them.
